Chicken Wing Dissection Lab

Purpose: To find and pair six different muscles in the chicken wing, in order to observe and understand the details of how muscles are involved in movement.

Dissecting Pan
Chicken Wing
Surgical Gloves

1. First, I put on my surgical gloves.
2. Then, I gathered all of the materials needed for this lab. 3. Before dissecting, I noted how the chicken wing appeared. I recorded these characteristics. 4. I then began the dissection by skinning the chicken wing. This allowed me to observe the fascia. 5. After skinning the chicken to the point where I could see the epimysium, I began using the forceps to pull on the individual muscles. 6. Once I found the different muscles that cause movement, I took notes and drew diagrams of the muscles. I then labeled which muscle was contracting and which was relaxing. I also labeled which muscle was the flexor and which was the extensor. 7. After finishing all of the directions given, I then disposed of my chicken wing in the designated trash can. 8. Then, I washed my dissection pan, forceps, and lab station. 9. Finally, after everything was completed, I washed my hands with soap and water.
